Atri -My Dear Moments-

A Sudden sea rise in some of the coastal areas of the Japanese lead a lot of human civilization to underwater. There was a survival boy, Ikaruga Natsuki who survived that but lost his family and one of his legs. After that, he came back to that city to met his old countryside. He found just a ship and submerged and his grandma left a huge debt behind that he had to pay back. He wanted to fulfill his dreams and for that, he was searching in the laboratory of his grandma where they knew about the rumor. She is an Oceanologist and left a trease in the ocean. He went off in search of that treasure.

He found a Coffin in the ocean and inside that there was a girl with an Atri sleeping. She is a robot but her emotions and appearance are exactly like humans. She got feelings and emotions and she promised to be with him until he completed the final order of her master. She became his leg and many changes happened in the lives of that Boy and robot girl.
